HybridGeo enables our partners to provide homeowners with a complete hybrid geothermal equipment package: equipment, design, installation and support. No other company delivers a comprehensive Pool Geothermal System package like HybridGeo does. For more information about our technology and its applications, please contact us.
Heat Rejection Module
At the core of our Pool Geothermal System is a patented technology called the Heat Rejection Module. This technology is critical because it enables the system to cool and heat a home while keeping the pool at a comfortable swimming temperature during swimming season. It also extends the swimming season by providing free pool heating during the spring and fall.
Main Features


The Heat Rejection Module comes in 10-ton and 15-ton capacities, and can be shared by multiple heat pumps to ensure it can be sized right for any size home.
The Heat Rejection Module makes no more noise than a typical pool pump, and unlike a traditional air-conditioning condenser, can be placed anywhere relative to the home.
The largest of the different size units only weighs 460 lbs with water and has almost the same footprint as a modern air conditioning condenser.
The Heat Rejection Module can use reclaimed condensate water from the air-conditioner minimizing and in some cases eliminating its water consumption.
All the internal components of the Heat Rejection Module are built from non-corrosive materials making it ideal for corrosive environments like the gulf coast.
While the Heat Rejection Module is an evaporative system, its innovative design eliminates many of the typical maintenance issues associated with evaporative systems. It requires no special water treatment, algaecides, winter preperation, or annual component replacement (eg. filters).
All of our equipment comes with a standard 10 year warranty.
Submersible Lake Heat Exchanger
Our Lake Heat Exchanger is a high efficiency heat exchanger designed for lake, pond, and river use. We have designed the Lake Heat Exchanger as a modular system that is the easiest to install and maintain in the industry. HybridGeo has also patented our unique Submersible Heat Exchanger technology. This unique technology is the most efficient and practical means of installing a geothermal system that uses a nearby lake instead of costly ground loops. Learn more on our Lake Geothermal Systems page.
Main Features

Our Lake Heat Exchanger comes equipped with either a copper or our patented corrugated stainless steal heat exchanger, and is designed so each tube of the heat exchanger is fully exposed to the water to optimize its heat transfer ability.
Typical lake heat exchangers are built using polypropylene pipe that transfers heat inefficiently and as a result have large footprints. Because our heat exchangers are so efficient we can design them to be compact making them easier to install, maintain, and keep away from potential hazards.
In addition to having a compact design, our Lake Heat Exchanger also has a low profile and designed to allow water to flow through the heat exchanger preventing it from moving or even flipping over in locations with fast water currents.
Multiple Hybrid-Geo Lake Heat Exchangers can easily be piped together allowing us to meet the heating and cooling demands of any sized lake geothermal system.
In addition to its small size -which makes installation and maintenance easier, our Lake Heat Exchanger comes equipped with a ballast system similar to a submarine. The ballast system makes our heat exchanger easy to submerge during installation and surface for maintenance. This reduces both installation and maintenance costs.
